(1) For the 7970G to have full display brightness, the external power adapter is required. The 7970G can receive power down the LAN from any of the Cisco in-line power-capable blades and boxes; however, the display screen is "half bright" and therefore is not the recommended mode of operation.

The Cisco IP Phone 7902G is a single-line IP phone, with fixed feature keys that provide one-touch access to the redial, transfer, conference, and voice-mail access features. Consistent with other Cisco IP phones, the Cisco IP Phone 7902G supports inline power, which allows the

phone to receive power over the LAN. This capability gives the network administrator centralized power control—translating into greater network availability.

7902G

7905G

The Cisco IP Phone 7905G is a cost-effective, basic IP phone providing a core set of business features. The Cisco IP Phone 7905G provides single-line access and four interactive soft keys that guide a user through call features and functions via the pixel-based liquid crystal display (LCD). The graphic capability of the display provides a rich user

experience by presenting calling information, intuitive access to features, and language localization in future firmware releases. The Cisco IP Phone 7905G supports inline power, which allows the phone to receive power over the LAN. This capability gives the network administrator centralized power control, which translates into greater network availability.

7910G (Announced EOS: August 2004)

The Cisco IP Phones 7910G and 7910G+SW, two key offerings in the IP phones portfolio, bring state-of-the-art technology to voice

communication solutions. The Cisco 7910G and 7910G+SW are basic telephones designed primarily for common-use areas—such as

lobbies, break rooms, and hallways—that do not require specialized features. The Cisco

7910G+SW includes a two-port Cisco switch making it suitable for worker applications

requiring basic phone functionality, including a co-located Ethernet device, such as a PC.

This single-line phone also provides four dedicated feature buttons, line, hold, transfer, and settings, located

prominently under the display. A cluster of six feature access keys is located above the volume control rocker switch. The factory default configuration for messages (msgs), conference (conf), forward, speed dial (speed 1, speed 2), and redial can be programmed by a system administrator to perform other functions, such as Call Park, Call Pick-Up,

and Night Service, as well as additional speed dials and other traditional telephone features.

The Cisco Wireless IP Phone 7920 is an easy-to-use IEEE 802.11b

wireless IP phone that provides comprehensive voice communications in conjunction with Cisco CallManager and Cisco Aironet? 1200, 1100, 350, and 340 series of Wi-Fi (IEEE 802.11b) access points. As a key component of the Cisco AVVID Wireless Solution, the Cisco Wireless IP Phone 7920 delivers seamless intelligent services such as security, mobility, quality of service (QoS), and management, across an end-to-end Cisco network.

The Cisco Wireless IP Phone 7920 is equally adaptable for all mobile professionals, from managers on the move within an office environment to associates working in the warehouse, on the sales floor, or in the call center. Nurses, doctors, educators, and IT personnel can also increase their reachability as an ever-broadening range of industries adopt wireless LANs.

7912G

The Cisco IP Phone 7912G provides core business features and

addresses the communication needs of a cubicle worker who conducts low to medium telephone traffic. The Cisco IP Phone 7912G offers four dynamic soft keys that guide a user through call features and functions. The graphic capability of the display provides a rich user experience by providing calling information and intuitive access to features. In addition, XML applications deliver impressive applications and network data to the Cisco IP Phone 7912G display.

The Cisco IP Phone 7912G supports an integrated Ethernet switch, providing LAN connectivity to a colocated PC. In addition, the Cisco IP Phone 7912G supports inline power, which allows the phone to receive power over the LAN. This capability gives the network administrator centralized power control, translating into greater network availability. The combination of inline power and Ethernet switch support reduces cabling needs to a single wire to the desktop.

7920 Wireless

The Cisco Wireless IP Phone 7920 provides the first generation of wireless IP phones for Cisco's IP Communications

solution. The Cisco Wireless IP Phone 7920 supports a host of calling features and voice quality enhancements.

7935 Conference Station

The Cisco IP Conference Station 7935 couples

state-of-the-art conference room speaker-phone

technologies from Polycom with the Cisco

award-winning AVVID-voice communication

technologies. The net result is a conference

room phone that offers superior voice and

microphone quality, with simplified wiring and

administrative cost benefits which are derived

when converging voice, video, and data across

a common IP infrastructure.

The Cisco IP Conference Station 7935 voice instrument is a full-featured, IP-based, full-duplex hands-free conference station for use on desktops and offices, and in small to medium-sized conference rooms. This device easily attaches a Catalyst? 10/100 Ethernet switch port with a simple RJ-45 connection, and dynamically configures itself to the IP network via the Dynamic Host Control Protocol (DHCP). Other than connecting the Cisco 7935 to an Ethernet switch port, no further administration is necessary. The Cisco 7935 dynamically registers to the Cisco CallManager for connection services and receives the appropriate endpoint phone number, and any software enhancements or personalized settings, which are pre-loaded within Cisco CallManager.

7936 Conference Station

The Cisco IP Conference Station 7936 offers improvements over the

existing Cisco IP Conference Station 7935 with external microphone

ports, optional external microphone kit, newly audio-tuned speaker grill,

and a new backlit liquid crystal display (LCD) display. The optional

microphone kit includes two microphones with six-foot cords. This places

microphones across a 12-foot area, effectively expanding a suggested

conference room size of 20 feet by 30 feet. The new backlit LCD display

improves visibility in low light conditions. The display font size is also

adjustable for improved distant viewing.

The Cisco IP Phone 7970G demonstrates the latest technology and advancements in VoIP telephony. It addresses not only the needs of the executive or major decision maker but also brings network data and

applications to users without PCs. This state-of-the-art IP phone includes a backlit, high-resolution color touch-screen display for easy access to communication information, timesaving applications, and feature usage. It also enables customers and developers to deliver more innovative and productivity-enhancing Extensible Markup Language (XML) applications to the display. Access to eight telephone lines (or combination of lines and direct access to telephony features), a high-quality hands-free speakerphone, a built-in headset connection, both Cisco pre-standard Power over Ethernet (PoE) and IEEE 802.3af PoE are supported.

speakerphone, handset and headset. The Cisco IP Phone 7960G also features a large, pixel-based LCD display. The display provides features such as date and time, calling party name, calling party number, and digits dialed. The graphic capability of the display allows for the inclusion of such features as XML (Extensible Markup Language) and future features. The 7960G is multi-protocol capable (SCCP, SIP, MGCP).

The Cisco IP Phone 7940G, a key offering in the IP Phone portfolio, addresses the communication needs of a transaction type worker. It provides two programmable line and feature keys, plus a high quality speakerphone. The Cisco IP Phone 7940G also has four dynamic soft keys that guide users through call features and functions.

Phone expansion module 7914

Call coverage is a critical capability for

administrative assistants and others who must

monitor, manage, and cover the various status

of calls. This requires the ability to instantly

determine the status of a number of lines

beyond the six-line capability of the Cisco IP

Phone 7960.

The Cisco IP Phone Expansion Module 7914 extends the capabilities of the Cisco IP Phone 7960 with additional buttons and an LCD display. With this expansion module, you add 14 buttons to the existing six buttons of the Cisco IP Phone 7960, increasing the total number of buttons to 20 with one module or 34 when you add two Cisco 7914 Expansion Modules. You can use up to two Cisco 7914 Expansion Modules with a Cisco IP Phone 7960.
